Barely two months ago, Spain celebrated the latest title captured by its Davis Cup dynasty. But now the greatest power of the past decade must start to defend its crown once more. While their path does not look steep, other contending nations eye more imposing challenges to their hopes.

Spain vs. Kazakhstan: In its first year of World Group experience, the Kazakhs burst onto this grand stage by ambushing the Berdych-led Czech squad in a victory of David over Goliath. When David traveled to Argentine clay, though, their discomfort on the surface led to an emphatic shutout. Once again mired in clay, they face the nation most renowned for its success on the terre battue. But most of that success came from two players absent from Spain’s B-level squad in Oviedo, Nadal and Ferrer. As Spain enters an era of Davis Cup without its leading stars, the defending champions rely on the fading Ferrero and the enigmatic Almagro, together with the unremarkable Granollers and the second-tier doubles specialist Marc Lopez. Considering the quality of their competition and home-court advantage, Spain should advance routinely even with this relatively modest quartet. This easy draw provides a chance for the team’s comprehensive remodeling to coalesce before meeting stiffer resistance. ESP in 3

Austria vs. Russia: Not especially intriguing at first glance, this tie features no player in the top 30. Several curious subtexts lurk beneath its apparent mediocrity, however, including the narrative of Alex Bogomolov’s debut in Russian colors after controversially spurning the United States. The most reliable member of either squad in Cup action, Youzhny arrives with his spirits soaring from a Zagreb title and owns a 4-2 advantage over Austrian #1 Melzer. Likely to appear if needed in Sunday’s reverse singles is the Austrian resident Davydenko, whose aggressive ball-striking suits the indoor hard courts better than Bogomolov’s counterpunching style. Bereft of imposing singles #2s, the hosts will lean heavily on Melzer to participate in winning three rubbers, for they have little hope of survival if the tie hinges upon the 127th-ranked Haider-Maurer. While the streaky Austrian #1 could ride his lefty net-rushing to a heroic feat, he has won consecutive main-draw matches only once since last July. His best tennis almost certainly lies behind this 30-year-old Wimbledon doubles champion. RUS in 5

Canada vs. France: Like the Austrians, the Canadians pin their ambitions upon a single potential hero in Milos Raonic. Although Vasek Pospisil and Frank Dancevic have excelled on home soil before, one would not fancy their chances to win two singles rubbers from Tsonga and Monfils, even with the latter perhaps not fully fit. In the doubles, Canada might combine Dancevic’s net skills with the vast doubles expertise of Daniel Nestor, only a little less effective with age. Nevertheless, Franch also will bring a talented doubles pairing in Benneteau and Llodra, who have won titles together before and might out-serve the Canadians on these fast courts. Stirring internal Canadian controversy before the tie was fiercely patriotic advertising by Tennis Canada that irritated the country’s French-speaking citizens. The weekend’s action will unfold far from Quebec in the British Canadian city of Vancouver, though, notorious for fanaticism in other sports. Famously fallible throughout their history, the French Davis Cup team must ignore the distractions to showcase their more versatile talent. Outside the serve, Tsonga and Monfils have far more weapons than Raonic, who might upset one of them but seems unlikely to topple both without their assistance. Three best-of-five victories on three straight days represents a towering task for the towering Canadian. FRA in 4

Switzerland vs. USA: Whereas the previous two ties look more interesting upon further inspection than at first glance, this tie looks more interesting at first glance than upon further inspection. On the indoor clay in Fribourg, Federer and Wawrinka should tie knots around the one-dimensional American servers. Unimpressive at the Australian Open, neither Fish nor Isner will bring the level of self-belief necessary to overcome the Swiss master, although Isner did win two sets from Nadal at Roland Garros. A stronger competitor than formerly (except against Federer), Wawrinka still struggles with maintaining a positive attitude under pressure sometimes. One wonders a little how he will respond to the challenge of blunting the American serves under the gaze of his expectant compatriots. So far superior are the Swiss singles players on clay, however, that they could afford to burn understudies Chiudinelli and Lammer on the doubles while relying on winning three of four singles rubbers. (Thus far, however, they have slotted Federer and Wawrinka into that rubber as well.) Paired with Ryan Harrison rather than former partner Isner, Mike Bryan should spare the visitors from a shutout before they drift down to the playoff round once more. In a minor footnote, Harrison should benefit from the experience of playing a visiting Davis Cup tie as his maturation process continues. SUI in 4

Czech Republic vs. Italy: Surely seething to avenge their first-round loss last year, the former Davis Cup finalists probably can expect only one or two more seasons from their reliable duo of Berdych and Stepanek. A two-man team with remarkable success in doubles together, they will host a clay-loving quartet of Italians on fast indoor courts where their superior serves and aggressive tactics should make spaghetti out of Starace et al. After extending Nadal to four tight sets in an Australian Open quarterfinal, Berdych won the Montpellier title last week and has played more consistently impressive tennis over the last few months thane he generally does. Not to be outdone by his countryman, Stepanek won the Australian Open doubles crown with Leander Paes in a commendable late-career highlight. Boosted by their individual momentum, they should prove once again that divergent playing styles and divergent personalities can fuse in explosively effective fashion. Like the Swiss, the Czechs probably can afford to concede the doubles and rest their stars for the singles. CZE in 4

Serbia vs. Sweden: Neither of their nation’s #1s, Djokovic and Soderling, will play a role in this starless Belgrade weekend. So sanguine was Serbian captain Bogdan Obradovic about his team’s chances that he encouraged the five-time major champion to focus upon preparing for the majors and Olympics. All the same, two top-25 singles threats in Tipsarevic and Troicki add to doubles veteran Zimonjic in comprising a balanced squad that always shines most under Serbian skies (or roofs, in this case). Across the net stands no Swede in the top 250 of the ATP singles rankings, although Robin Lindstedt should duel intriguingly with Zimonjic in the doubles rubber. But otherwise we expect minimal suspense from the greatest mismatch of the weekend. SRB in 3

Japan vs. Croatia: A mismatch in height alone, this tie offers a second straight weekend of tennis in the Bourbon Beans Dome. Partnering Kimiko Date-Krumm in mixed doubles at the Australian Open, Nishikori will aim to emulate that legend’s success in Fed Cup against another Balkans team. Unexpectedly reaching the singles quarterfinals in Melbourne, the Japanese #1 should relish the rare opportunity to play before his home fans—at least more than the opportunity to blunt Karlovic’s serving power. The doubles looks even more uncertain than the singles rubbers, although perhaps the Croat’s towering serve will prove decisive by earning ample free points. In the first meeting between these nations, the straightforward power and forward movement of the visitors will contrast with the steady baseline resilience of the home squad. While the indoor hard court would seem to tilt towards Croatia, Nishikori and his compatriots will not surrender without a fierce struggle. CRO in 5

Germany vs. Argentina: Rebounding from a valiant but doomed effort against a Nadal-led Spain in last year’s final, the perennial bridesmaids of Davis Cup begin yet another Sisyphean quest towards its elusive summit. Curiously without their flagship Del Potro, a key factor in their semifinal victory over Serbia in 2011, Argentina will rely one more time upon Cup stalwart Nalbandian against a German team lacking its most dangerous player in Kohlschreiber. Considering the characteristics of Mayer, Petzschner, and Haas, one must query the host country’s decision to put Monaco and Chela on their favored red clay. Fast-court players who prefer short points, the Germans would seem at a disadvantage against the Argentine clay specialists. Also notable is the age of the participants, of whom the youngest (Monaco) will turn 28 next month. Under the rigors of the best-of-five format on a slow court, fatigue and injury may play a role for some of these veterans. As with Japan vs. Croatia, either team could win any of the rubbers. But only one of these players, Nalbandian has compiled a history of Davis Cup heroics, and he should lift his nation again in a tie that looks less formidable than it did when the draw first appeared.
